Luehr - Vacuum Valve

In some applications an effective, low cost, minimal maintenance alternative to rotary valves or double dump valves on the dust collector hopper outlet is the Luehr Vacuum valve. The valve operates when the head of material added to the pressure of the pulsejet cleaning cycle creates enough pressure to open the moulded rubber sleeve allowing the material to fall out. The vacuum in the dust collector hopper otherwise holds the rubber sleeve closed. They can also function in solely gravity applications.
